MEANS FOR MOUNTING RAILWAY CAR HAND BRAKES Application filed May 27, 1926. Serial No. 111,999.

My invention relates to railway car hand brakes, and more particularly to means for mounting the hand operated mechanism on the car.

The primary object of the invention is to provide improved means for mounting hand brake operating mechanisms on railway cars, whereby the mechanism maybe so po sitioned on the car body as to obviate many of the inconveniences and dangers of injury heretofore encountered by railway brakemen when operating the hand brake mechanism of a car, and whereby the brake operating mechanism may be readily applied to the end wall of a railway car without requiring any substantial change in the car construction.

The invention consists in the new and improved arrangement and the construction and combination of parts hereinafter described and claimed for carrying out the above stated objects and such other object as will appear from the detailed description of the embodiment shown in the annexed drawing. I

In the drawing,

Fig. 1 is a vertlcal section through the end portion of a gondola car showing a preferred means for "mounting the brake operating mechanism upon the corrugated end wall of a car.

In the drawing, I have shown a hand brake operating mechanism applied in accordance with my invention to a railway gondola car. It will be obvious, however, that the advantages of the invention herein shown are not confined to its use on the particular type of car on which it is illustrated. Referring to the drawing, 10 designates the sheet metal end wall of a railway car, 11 the end sill, and 13 the brake step. The brake operating mechanism herein shown is preferably the same in construction as that shown and described in my copending application Serial No. 109,061 filed May 14, 1926. It consists of a casing 15 in which is enclosed winding mechanism (not shown) adapted to be operated by means of the vertically disposed r hand wheel 16.- A chain 17 isconnected at one end to the winding mechanism so as to be wound thereon, and is connected at the other end with the upper end of the rod 18*. The lower end of the rod 18 is attached to one end of the bell crank 19 secured to the under side of the car end sill structure 11, and operatively connected to the brake rod chain 20 of the brake rigging of the car.

The brake step 13 is positioned on the end wall of the car so that the head and shoulders of the brake-man will project above the 69 car when the brake-man is standing on the brake-step. The casing 15 of the brake operating mechanism is secured to the end wall of the car in such position with respect to the top and side of the car, that the brakeman when standing on the brake step and gripping the upper edge of the car with his left hand, can grasp the spokes 22 of the hand wheel 16 and operate the wheel with lifting movement without obstructing his 79 view above the car.

In the arrangement shown in the'drawing, the bell-crank 19 is secured by a bracket 25 to the end sill structure 11 0f the car in longitudinal alignment with the brake rod' 23 of thebrake rigging.

The mechanism casing 15 is attached to the corrugated end wall of the car, by means of U-shaped brackets 28. Each of the brackets is provided with a projecting web 29 which extends between the casing 15 and the crest of an adjacent corrugation. The extended web rigidifies the margins of the casing.

The brake step 13 is preferably slotted, as indicated by the reference character 30, for the rod 18*.

The combination of the winding mechanism and bell crank; vertical hand wheel and power increasing take-up mechanism; the position of the release lever relative to the 90 housing and vertical hand wheel; the housing construction; and the bell crank construction are not claimed herein apart from the means herein disclosed for mounting the said hand brake mechanism on the car. The said combinations and improved constructions are claimed in the order above noted in my copending applications as follows: Serial Nos. 109,061, filed May 14, 1926; 349,817, filed March 25, 1929; 431,762, filed February 100 27, 1930; Patent No. 1,8705985, dated August 9,1932 and application Serial No. 560,407, V. filed Aug. 31, 1931.

I claim:

5 In combination with a brake rigging and the corrugated end wall of a railway car, a hand brake for operating said brake ri ging comprising a housing, a hand wheel, and a flexible connector adapted to be tightened by rotation of said hand wheel, and means for securing said housing to the end wall of the car comprising a U-shaped bracket, one flange of which is secured to the flat marginal portion of the wall and the other flange of which extends over and is secured to the crest of an adjacent corrugation.

RICHARD W. BURNETT.
